Greco-Roman meteorology will be described in four overlapping developments. In the archaic period, astro-meteorological calendars were written down, and one appears in Hesiod’s Works and Days; such calendars or almanacs originated thousands of years earlier in Mesopotamia. In the second development, also in the archaic period, the pioneers of prose writing began writing speculative naturalistic explanations of meteorological phenomena: Anaximander, followed by Heraclitus, Anaxagoras, and others. When Aristotle in the fourth century BCE mentions the ‘inquiry that all our predecessors have (...) been calling meteorology’ (338a26), he is referring to these writers. In the third development, the first two enterprises were combined: empirical data collection about meteorological phenomena began to be married to naturalistic theoretical explanation. This innovation was prompted by Democritus and synthesised in its most influential form by Aristotle. At this point more sophisticated techniques of both short-term weather forecasting and long-term speculation about global climate change were also developed. In the fourth development, the wider implications of the naturalistic explanation of meteorological phenomena were contested. The views of ‘meteorologists’ had been controversial since the archaic period because they were perceived, and sometimes intended, to displace the divine prerogatives and undermine traditional religion. These controversies intensified throughout the classical and Hellenistic periods. (shrink)

Encyclopedia article on Democritus. Includes a brief overview of his philosophical views, major works, and critical reception.

Hynek Bartos does the field of ancient philosophy a great service by detailing the influence of early Greek thinkers (such as Heraclitus, Empedocles, Anaxagoras, Democritus, and Diogenes of Apollonia) on the Hippocratic work On Regimen, and by demonstrating that work’s innovative engagement with contemporary scientific and philosophical concepts as well as its direct influence on Plato and Aristotle. His study usefully counteracts the lamentable tendency among ancient philosophers to ignore or downplay the influence of medical literature on philosophy in general, (...) and to heap scorn on this text in particular, which Kirk, Raven, and Schofield considered ‘an eclectic and very superficial quasi- philosophical treatise’ and Barnes famously called ‘a silly farrago of ill-digested Presocratic opinions’.

Digital technologies not only to transform the social and cultural reality; they are making changes in the human nature. Therefore, it makes sense to speak about Silicon Race (SiRace). Iron men descends from the world history scene. This process is irreversible, but realizing in emerging with the prospects and the risks that accompany them, we can direct the efforts to ensure that reforging the iron men will be successful.

Contribution on Peri ton areskonton philosophois physikon dogmaton (Placita philosophorum), 2nd c. CE, based on a work by Aetius, falsely attributed to Plutarch.

The reductio ad absurdum has been elected by Zeno as the only method permitting to descry the true reality, invisible both to the senses and to the common way of thinking. Showing some continuity with the previous philosophers, not only in the search for a procedure in order to speculation to advance, but also on the same route departing from what is nearer, more acquainted and particular (visible) toward what is less acquainted, more distant and universal (invisible), to say it (...) with aristotelic words, Zeno made use of aporetic arguments as the only possible way to catch a glimpse of the ‘domain of Being’. This, in fact, is invisible not only to our senses, but also to our ordinary reasoning. Therefore, just the ‘way of not-being’, the only one that could be walked after Parmenides, as Wolff says, allows us to have an insight of what is ‘really invisible’. So invisible that it is unreachable also to thought. (shrink)

The poiintt of Democritus' physiology of the eye is that vision occurs because the eye allows the image in, and its sponginess aids the transmission of the image to the reasoning faculty. Thus,, Democritus' ophthalmology plays an important, though neglected, part in his theory of vision.

In the analysis of Anaxagoras’ physics in view of the relation between his teachings on multitude and heterogeneity, two central questions emerge: 1) How can the structure of the universe considered purely mereo-topologically help us explain that at the first cosmic stage no qualitative difference is manifest in spite of the fact that the entire qualitative heterogeneity is supposedly already present there? 2) How can heterogeneity become manifest at the second stage, resulting from the noûs intervention, if according to fragment (...) B 6 such a possibility requires the existence of “the smallest”, while according to the general principle stated in fragment B 3 there is not “the smallest” but always only “a smaller”? This paper showcases the perplexity of these two questions but deals only with the former. The answer follows from Anaxagoras’ being a thoroughgoing infinitist in the way in which no Greek physicist was: the principle of space isotropy operative in geometry is extended to physics as well. So any two parts of the original mixture are similar to each other not only in view of the smaller-larger relation but also because each contains everything that the other one contains. This in effect means that at the stage of maximal possible heterogeneity each part of any part contains infinitely many heterogeneous parts of any kind whatsoever. So, neither can there be homogeneous parts in view of any qualitative property, nor can there be predominance in quantity of parts of any kind that would make some property manifest. (shrink)

A new assessment of the philosophical traditions Hippolytus depends on and of his method of presentation. This book deals with the reception of the Presocratics, Plato and Aristotle in the first centuries CE, and is a major contribution to our knowledge of the various currents in Pre-Neoplatonic Greek philosophy.

Recently a view of Hegel’s “idealism” which hitherto had seemed unquestionable—the view that it is fundamentally a metaphysical doctrine—has been seriously challenged. Thus yesterday’s metaphysical Hegel, complete with his cosmic megasubject hidden behind the events of nature and history, has been joined by today’s “nonmetaphysical Hegel,” the postkantian categorial “genealogist.” According to the nonmetaphysical Hegelians, a century and a half of misunderstanding has been based on the confusion of two distinct philosophical projects: on the one hand, that originating in the (...) Aristotelian project of “ontology”—the reconstruction of the categorial structure of to on e on, “being qua being”—and on the other, that stemming from the very different Aristotelian project of “theology”—the investigation of to theion, primary being or that which is first in the order of substances.

This book is part of the series ‘Classical Life and Letters’ and is thus intended for the general reader. Consequently, the book gives a survey of major figures and topics in Presocratic philosophy; the structure of the book appears from the headings of the eight chapters: Introduction, The Milesians, Heraclitus, Pythagoras and the Greek West, Parmenides and Zeno, The Age of the Sophists, Cosmology from Parmenides to Democritus, Conclusion: the Study of the Presocratics. Hussey leaves out most of the biographical (...) details and makes no attempt to present the evidence, either the actual fragments or the testimonies, independently of his own interpretations. The fragments are often broken up so as to suit his interpretation which is generally given before the fragments., thus sometimes misleading the reader. Hussey frequently acknowledges that there is no good evidence for what he is saying, and he does a lot of reconstructing and poses questions which do not seem to have been raised by the Presocratics themselves.
